Translation according to P. W. Joyce:
Omey Island in Galway; called in the Records Iomhaidh Feichin, which is believed to mean Feichin's bed or seat. For St. Fechin is patron, and lived on the island, where a church was built over his bed. See Emy [reproduced below].
Emy, the first and proper name of Emy Vale in Monaghan. The Irish Iomaidh [Eemy] means a bed or couch, and it was sometimes applied to a church erected in veneration over the little apartment, where, during life, a saint was accustomed to sleep. For example, there was a church at Clonmacnoise called Iomdhaigh-Chiarain, the bed of St. Ciaran or Kieran, the founder. See Omey.
